How to choose an amplifier for the reference of a Data Converter?

Hi,

As you know,If the Data Converters use an external reference,sometimes we may use an amplifier as a buffer. 

There are some questions as below:

1.Why do we use an amplifier as a buffer for the external reference?

2.How to choose a right amplifier? What parameters must be considered?

Thanks! 

  • Hi,

    The Reference Driver Design section of this document (TIPD115) gives a comprehensive description of the key equations and parameters related to the design of the amplifier to buffer the external reference.

    I hope this helps.

    Regards,

    Sandeep
